That is not even close to the explanation of what a properly implemented Atherton/ Bob Mullen crossover is claimed to do.
I have seen all kinds of crossovers, anything from braid line with 90 degree aero quip fittings. That's why I said properly implemented.
The Atherton crossover requires precise exit and entrance angles.
It is claimed that these angles precisely channel a certain amount of oil to the drivers side to slow the oil speed on the passenger side to better allow the oil to make it to number four main. Not just any old crossover will work.
